Microwave with Photocell
Only suitably qualified personnel should install this equipment.
The K4025 is a high-performance, communicating presence detector. The
K4025 is equipped with a regulating photocell to control digital DSI ballasts
(when using the K4025’s Digital Output) and a volt-free output for control of non-
dimmable lighting loads. The K4025 incorporates OneSwitch Dimming, local
manual operation of any controlled lighting load.
Installation and Commissioning
Instructions
Note: K4053 or K4050 required for commissioning

Flush
Location
The K4025 is an extremely sensitive movement detector; it is essential therefore
that it be installed on a rigid surface that will not itself be subject to movement or
vibration.
Please note that K4025 is not recommended for applications where there are
large surface areas of metal, e.g. metal ceiling or floor tiles, as unpredictable
sensitivity may result.
The units are graded according to four variations in operating frequency. Each
type can be identified by different colour-coding on the detector label and carton.
For reliable operation it is essential that units of the same colour code do not
occupy adjacent positions in open-plan areas (see example below).

Electrical Connections
OneSwitch
K4025 should be connected in accordance with the diagrams overleaf.
K4025 is designed to control up to 25 DSI luminaires, a switched load of up to 6
Amps or a combination of the two. The DSI input terminals on the ballasts should
be connected in parallel with each other and to the Polarity-Free Digital Output
terminals on the rear of the K4025. Each DSI luminaire is controlled completely
by its digital input and therefore would normally have a permanent power supply.
Turning the power off to some lights within a control circuit will not have affect the
operation of those lights that remain powered up and under the control of the
K4025.
When switching via the volt-free output multiple K4025s may be connected in
parallel provided the controlled load does not exceed 6 Amps. If digital ballasts
are also being controlled the digital outputs from each detector must not be
mixed even if they are of the same type.
OneSwitch Dimming affords local control to the end-user whereby a simple,
momentary, push-to-make wallswitch can be used to raise or lower the lighting
level or toggle the output of the unit ON or OFF. A short press (less than
1 second) toggles all outputs from
OFF to
ON or from
ON to
OFF. A long press will ramp the digital output either up or down with no effect on
the volt-free output. If the output prior to pressing the switch is above 90% the
output will ramp down; if below 90% it will ramp up. If the latest press and the
current press are within 5 seconds of each other it will ramp in the opposite
direction. A latching switch can be used to override the outputs OFF or ON at
maximum output.
